Abstract
The synthesis and biological activity of indoloazepines and acid amine salts thereof which are structurally related to naturally-occurring hymenialdisine is disclosed. Naturally-occurring hymenialdisine obtained from the sponge is a potent inhibitor of production of cytokines interleukin-2 (IL-2) and tumor necrosis factor-α (TNF-α). The chemically-synthesized indoloazepines of the invention also inhibit production of IL-2 and TNF-α. The indoloazepines are useful for treating inflammatory diseases, particularly diseases associated with kinases NF-κB or GSK-3β activation or NF-κB activated gene expression products. The indoloazepines are useful for the treatment of cancer by the inhibition of kinases CHK1 and CHK2.
Claims6
A method for treating an animal with an inflammatory disorder wherein said inflammatory disorder is selected from the group consisting of rheumatoid arthritis, inflammatory bowel disease, asthma, dermatosis, and organ rejection, said method comprising inhibiting production of a cytokine in cells of an animal, said cytokine selected from the group consisting of interleukin-2, TNF-α and combinations thereof, by administering to said animal a compound of the formula
- and acid amine salts thereof wherein R1, R2, and R3 are each selected from the group consisting of hydrogen, alkyl containing 1 to 6 carbon atoms, halo, aryl, hydroxyl, amino, SH, carboxyalkyl, alkoxy and carboxyamido moieties in an amount sufficient to inhibit production of the cytokines.
